CLASS I COMPONENTS
6 General
6.1 Class I components shall be made of copper, copper alloy, aluminum or aluminum alloy with hardware made from stainless steel, unless otherwise required in this Standard, as outlined below:
a) Copper conductors and air terminals shall be made from electrical grade copper. Cli 000, generally designated as being 95% conductivity when annealed.
b) Aluminum conductors shall be made of electrical grade aluminum, with a minimum chemical composition of 99% aluminum.
C) Aluminum air terminals, stainpings and couplings, shall be made with an alloy having a minimum chemical composition of 90% aluminum.
d) Stainless Steel hardware, such as nuts, bolts, washers, screws, threaded rods, and fasteners
shall be of minimum 18.8 grade (Chromium & Nickel content) with acceptable alloys being 302,
303 and 304.
e) All copper alloys other than brass shall have a minimum copper content of 80%.
f) Aluminum alloys suitable for use in castings shall have a minimum aluminum content of 85%.
g) Brass alloys suitable for use in couplings. connectors, bases and fittings shall have a minimum copper content of 60%.
7 Air Terminals
7.1 An air terminal may be of one piece construction or may have several separate parts including: point (tip portion), elevation conductor, and base support.
7.2 An air terminal shall not be less than 254 mm (10 in) long and shall comply with the requirements in Table 7.1.
